The exact malayalam text in mnglish Line 15 : Ennal panam kodukkate mikacha software aarkkum nalkunna oru prasthanam undu. Athanu free software foundation. Free software prasthanathile prashastharaya 2 peranu richard stallman um Linus Torvaldsum
Using the English words "free software" is a mistake because of the ambiguity in the word "free". How do you say "free" (as in freedom) in Malayalam? That is what they should use, not "free".
